In September 2022, 23 organisations from 12 European countries started a joint effort in the DIAMAS project to better understand the institutional publishing landscape in the European Research Area (ERA); and provide the institutional publishers and service providers (IPSPs) with support to better align their practice, improve quality, and develop sustainability. This action will facilitate the work of researchers by providing them with an aligned, high-quality, and sustainable scholarly communication ecosystem, capable of implementing Open Access as a standard publication practice. The DIAMAS project, funded by the European Commission (EC) under the Grant Agreement ID 101058007, has a duration of 36 months organised into three distinct phases: 1. Understanding the landscape of IPSPs in the ERA. 2. Improving coordination, quality and sustainability of IPSP. 3. Formulating policy and strategy recommendations. This policy brief, released at month 35 of the project, reflects on the lessons learnt during the second phase of the project, and formulates recommendations based on the project participants' experience so far. 

Deliverable under the review of the European Commission.
